Abstract (en)

[origin: US2003234573A1] A controlled brake apparatus and method of operating a brake apparatus utilize a pre-charge circuit connected directly between the fluid reservoir of a master cylinder of the apparatus and the inlet of a controlled braking pump, to thereby direct pre-charge flow and pressure to the controlled braking pump inlet in a parallel circuit relationship to a primary hydraulic circuit, rather than in a series flow arrangement through the primary hydraulic circuit as was the case in prior brake systems. The pre-charge circuit includes an integral back-flow check valve, and an accumulator.
